Take the last two feet of rope (from the end) and make a simple S-shape. Take the end of the rope and create two bends, forming an S-shape with the rope. The standing line should be left long so that you have some string left at the end. Take the standing line of the rope and pass it under all three sections of the S. Simply take the top end of the rope and bring it under everything so that the S-shape in your rope rests on top of the standing line. This will slightly "ruin" the S shape -- what is important are the two bends. Loop the end of the rope back around the top of the S-shape of rope and then back under. This is the first of the many "wraps" that sit at the top of the knot. This is one revolution. Pull it tight, so that there is still the loop on one end. Continue wrapping the rope around the S-Shape of rope 6 or more times. Be sure you have an odd number of loops. You must have at least 2-3 inches of the end of the rope left over when done. Pass the end of the rope through the bottom loop of the knot. The bottom loop means the loop next to the standing line of rope, leading away from your knot. Tuck the end of the rope through this bight. Pull on the knot and standing line to tighten. This will also expand your loop hole, tightening the entire knot so that you're just left with the rope, the coils, and the knot. Once tightened, this knot is strong and difficult to undo.If the loop isn't big enough, you should start over, making a larger S-shape than before.
